So, i have two objects:

var object1 = $('div');
var object2 = {};

How i can define is this jQuery object, or not?

for javascript version < 1.4

Answer

var abc={};

if(typeof(abc.jquery)=="undefined"){

console.log("object is not a jquery object");

}else{


console.log("object is a jQuery object");

}

if object is jQuery object then

objectIdentifier.jquery =< version of jQuery>
